The study explores teachers' views on the impact of the English Language Proficiency Programme in Namibian schools that was implemented over a period of five years, from 2011 to 2015. The program aimed at improving teachers' proficiency in English. The summative evaluation was conducted in 2016 in the following five (5) regions: Erongo, Hardap, Khomas, Ohangwena and Omusati, selected on the basis of the level of participation and accessibility. The evaluation focused on the following aspects of the project: program development, program implementation and administration as well as assessment of learning outcomes. The study followed a qualitative approach using document analysis to inform the development of evaluation instruments and a phenomenological design to assess teachers' lived experiences during program implementation. Data was collected through focus group discussions among teachers. The study established that teachers did not appreciate the program as it was ill-planned, irrelevant to their needs and disturbed their daily routines. Nevertheless, a few teachers embraced the program and reported positive benefits in terms of teachers' career development goals. The study recommends the revision of the program in terms of content and implementation procedures. In addition, teachers' support systems, learning materials and the mode of delivery need improvement to effectively enhance teaching and learning in Namibian schools.
